New built desktop issue! Fan powers on off.

Hi, just built a new desktop, but when I power on, all the fans power on, then off, and repeats. No sound from motherboard (but I only have a TV monitor so the sound probably not transmitted?). How do I fix this? Here are the parts

Case: Enermax Coenus ATX Mid Tower Computer Case
CPU: Intel I5 6600
Motherboard: GA Z170XP-SLI
Ram: Crucial Ballistix Sport LT 16GB Kit (8GBx2) DDR4 2400 MT/s (PC4-19200) DIMM 288-Pin - BLS2K8G4D240FSB (Gray)
Hardrive: Samsung Evo 850 500gb (Cloned previous harddrive which has Win 7)
PSU: 450W Antec


No optical drive. No separate GPU.

Edit: tried disconnecting everything except motherboard and CPU, attached to a monitor. Same issue

possible you have a grounding issue take the motherboard out of the case then power it on.

you have a screw or something that is grounding the board to the case

You don't need external speakers to hear error code beeps from the motherboard. There's a tiny beeper on the board itself. So if you aren't getting any beeps, then the boot process is getting stopped VERY early in its routine.

A few things to check:

Are you certain that the CPU is properly seated and that there are zero bent pins on the CPU socket?

Is your CPU cooler actually touching the CPU? If not installed correctly they can sometimes not quite be in contact with the CPU. Without the cooler, the CPU will go into thermal shutdown almost instantly.

Are you certain that all of the wires for LED's, switches, etc. are connected to the right pins on the motherboard?

Power supply connector is fully seated and locked into place?

Agree with above

also try one ram at a time
make sure the CPU power plug is in. I would unplug all connectors and plug back in

Does that MOBO have the BIOS reset button on board?

If you bought that board for SLI you wasted some $$ with the new cards capability

Also, do the lights on the MOBO light up. can you keep it from doing the cycle or does it start doing it as soon as cord plugged in

What's SLI? I bought it cause it was on sale hahah

I dont see any lights light up on mobo, no beep either

It does have CMOS reset which i did a few times. It doesn't have bios reset as far as i can tell but it does have main bios and backup bios.

I checked the cpu, fitted in pretty well. refitted everything and fan, touching well .

It starts cycling as soon as I turn on the computer

looks like this motherboard doesn't have a built in piezo beeper, it uses the speaker pins in the front panel connector.

Do the fans turn on and off repeatedly themselves or turn back on briefly after you press the power button again?

On and off themselves. It would spin fast, then stop, then spin fast.

Yea it has no built in speakers. the case doesn't come with pins to connect to the speaker part so i guess MB beeps is not happening for me

Pins in this connector may not quite right for your motherboard but it could be made to work

you could use an old case or even just measure the voltage on those pins with a multi meter (don't accidentally short something).

My money's on some kind of power or grounding issue. Try searching youtube for things like "troubleshooting new computer build"

might still be the motherboard. how can you not get a signal from the motherboard if its working ok.
